We've just released Dev Proxy v0.29.0-beta.2 with our language model prompts exposed. If you choose to use a different model than llama3.2 which we use by default, you can now update prompts to match your model's capabilities. Try it and tell us what you think! github.com/dotnet/dev-p...

Prompty offers you a great way to separate your prompts from your code, simplifying testing and observability. Foundry Local is a new tool that allows you to run language models on local devices. Here's how you can use them together: techcommunity.microsoft.com/blog/azurede...

Encoding matters. This caught us during our recent demo at CloudSummit: while submitting an emoji in an API request emulated using @devproxy.bsky.social we got a broken response. Turns out, emojis are utf-8 and need a proper encoding. Change the content-type to include the encoding and avoid errors.

We've just released a new pre-release version of Dev Proxy Toolkit for use with v0.29.0-beta.* releases - Dev Proxy MCP Server - Support for upgrading via package manager - Update snippets schema versions to v0.29.0 and use new DLL name marketplace.visualstudio.com/items?itemNa...

TIL that @anthropic.com publish the system prompt in the release notes for Claude. If you are building agents and want to have better behaviours, there are some great examples to follow. docs.anthropic.com/en/release-n...

It was great to share the stage earlier this week with @wldk.nl and @paolopia.bsky.social at ECS to deliver a full day workshop on Microsoft 365 Copilot extensibility using VS Code.

Thanks @scott.hanselman.com and @markrussinovich.bsky.social for the latest episode of Scott and Mark Learn To...Feedback So much gold here about taking feedback it is a very good watch. Stand out moment is Mark's reaction to "Don't interupt me" 🙌 youtu.be/yYcEiNkdkyo?...

I'm a big fan of both DevProxy and Aspire, so it's great to see them working well together! Add DevProxy support with just one line of code in your Aspire configuration. #aspire #dotnet #devproxy
